This is an open-label, multicenter, randomized, crossover study. Patients are stratified according to study site and cytogenetic response to prior imatinib mesylate (yes vs no). Patients are randomized to 1 of 2 treatment arms.
- Arm I: Patients receive oral BMS-354825 twice daily in the absence of disease progression or unacceptable toxicity. Patients experiencing disease progression or persistent intolerance to BMS-354825 cross over to arm II after a 2-day washout period. After crossover, patients receive oral imatinib mesylate twice daily in the absence of further disease progression or unacceptable toxicity.
- Arm II: Patients receive oral imatinib mesylate twice daily in the absence of disease progression or unacceptable toxicity. Patients experiencing disease progression, intolerance to imatinib mesylate, lack of major cytogenetic response at 12 weeks, or < 30% absolute reduction in Philadelphia chromosome-positive metaphases at 12 weeks cross over to arm I after a 1-week washout period. After crossover, patients receive oral BMS-354825 twice daily in the absence of further disease progression or unacceptable toxicity.
Quality of life is assessed at baseline, at day 29, every 4 weeks for 24 weeks, every 12 weeks for the remainder of study treatment, and then at the completion of study treatment.
After the completion of study treatment, patients are followed for at least 30 days.

Note: The purpose of most clinical trials listed in this database is to test new cancer treatments, or new methods of diagnosing, screening, or preventing cancer. Because all potentially harmful side effects are not known before a trial is conducted, dose and schedule modifications may be required for participants if they develop side effects from the treatment or test. The therapy or test described in this clinical trial is intended for use by clinical oncologists in carefully structured settings, and may not prove to be more effective than standard treatment. A responsible investigator associated with this clinical trial should be consulted before using this protocol.
